Yes, the pressure makes a difference but at a price.

There a starting to be a LOT of injector body failures when pressure boxes are used. Be careful how far you turn them up and long you run them high.

On the street and daily drivers TURN THE PRESSURE DOWN or you will fatugue the injectors much faster. Bosch has made a change in metal composition of the bodies and tips for a very good reason.

 

also be careful on running timing on both the edge and smarty . know a guy that burned cylinder #6 because of the double timing

 

I keep the edge on "stock" when I am using the smarty power. I will sooner or later disconnect the edge and sell it.

 

Which model did you buy TX?
What air intake and exhaust are you running?

Anybody know what advantage timing or no timing has? I thought extra timing was good for MPG?
